Hydrogen sulphide and salicylic acid regulate antioxidant pathway and nutrient balance in mustard plants under cadmium stress.

Plant biology, 2021
Cadmium (Cd), a pervasive noxious heavy metal, is a key threat to agricultural system. It is rapidly translocated and has detrimental effects on plant growth and development.

Nutrient Balances of Rewetted Fens – Groundwater Lysimeter Results 

XXV International Grassland Congress (IGC 2023), 2023
With the raising of groundwater levels to protect fens and the climate, there may be a risk of nutrients, such as nitrogen or potassium, leaching into the groundwater. Great amounts of nutrients, which are accumulated largely by peat forming plants like Phragmites australis and Carex spec., are conveyed into rewetted fens through high amounts of ...

Integrated nutrient management (INM) on yield trends and sustainability, nutrient balance and soil fertility in a long-term (30 years) rice-wheat system in the Indo-Gangetic plains of India

Journal of plant nutrition, 2018
We analyzed data from a long-term rice–wheat cropping sequence to evaluate the effects of integrated nutrient management (INM) on yield trends and sustainability, nutrient balance and soil fertility of the system.

Treatment for Obesity: A Nutrient Balance/Nutrient Partition Approach

Nutrition Reviews, 2009
This paper examines the treatment of obesity, using a feedback model of nutrient regulation. A feedback model contains afferent signals and a central controller that transduces afferent information into efferent signals that modulate the controlled system.

Hypothalamic Nutrient Sensing and Energy Balance

2009
Hypothalamic neurons have the capacity to sense and alter their activity in response to fluctuations in local nutrient concentrations. Alterations in glucose, fatty acid and amino acid concentrations have all been demonstrated to affect neuronal excitability and/or intracellular signaling pathways.

NUTRIENT BALANCES IN FIELD VEGETABLE PRODUCTION SYSTEMS

Acta Horticulturae, 2003
In this review paper an overview of the nitrogen (N) and phosphorus (P) cycles in agricultural systems is presented. The information summarized provides general information on the important processes involved as they relate to losses from agricultural systems.

Balancing act: Understanding nutrient interactions

World Journal of Biology Pharmacy and Health Sciences
Nutrient interactions refer to the dynamic relationship between various nutrients, including minerals, vitamins, amino acids, and fatty acids, for proper functioning. An excess or deficiency of one nutrient can affect the requirements for many others, and increasing or decreasing a deficient nutrient may require an increase in other nutrients.
